John Timmer reported on a study done of the life expectancy of rock-stars:

In general, richer people have longer life expectancies than the general population; and rock-stars are quite rich.

However the data shows that being a rock-star completely negates the benefits of being rich, and in fact, lowers your life expectancy when compared to the general population.

European rock-stars have a longer life expectancy than American ones, but European rock-stars still have a lower average life-expectancy than the general European population for the first few decades of their life.

However, after 35 years of fame, European rock-stars had the same life expectancy as average Europeans.

In general difficult childhood circumstances led to a greater likelihood of rock-stars dying of substance abuse or other risky behaviour.

This suggests that being a rock-star isn’t what leads famous musicians to engage in excessive drinking, drug abuse, or suicide. Rather it’s traumatic childhoods that causes it.
